Comparative map of the keratin type II gene cluster.

<p>Type II keratin genes and <i>KRT18</i> in the dog (CanFam3.1), human (GRCh38.p2) and horse genomes (EquCab 2.0). Arrows indicate the orientation of the genes. Note that CFA 27 is represented in reverse orientation with decreasing coordinates from top to bottom. The genes’ nomenclature in the figure corresponds to our updated nomenclature for keratin genes (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0180359#sec002" target="_blank">Methods</a>). <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0180359#pone.0180359.s009" target="_blank">S3 Table</a> details the correspondence of gene symbols to NCBI Gene IDs and RefSeq IDs.
